refactor got log -d and tog diffstat to compute diff once This eliminates the previous performance cost by making 'got log -d' and tog diff view compute the diffstat while building the diff in a temp file like we do with 'got diff -d'. Also, keep the current 'got log -d' UI as per stsp's suggestion. ok stsp@

don't use plural noun after 1 in diffstat total Use singular form when appropriate; for example, turn the top into the bottom: 1 file changed, 1 insertions(+), 1 deletions(-) 1 file changed, 1 insertion(+), 1 deletion(-) ok op@

tog: fix {first,last}_displayed_line dead store Both are already assigned just above in open_diff_view() ok op@

typo: zap double semi-colon

got: minor refactor of got_pathlist_free() API Accept flag parameter to optionally specify which pointers to free. This saves callers looping through the list to free pointers. ok + fix stsp@

got: expand diffstat -d option to 'got diff' Like got log -d, add the switch to 'got diff' to display a diffstat of changes; as per stsp's suggestion, we always include diff output with the diffstat. Disabled in gotwebd (for now :) Includes tweaks from op@ ok stsp@

tog: add mutt-like =/* keymaps as home/end aliases Also, separate g/G from home/end in the manual and runtime help text as only the former accept a prefixed count modifier. Based on initial diff from Mikhail. ok stsp@

show from: and via: headers on consecutive lines in 'got log' and 'tog log' ok jamsek

got: implement diffstat for got log and tog diff view Add new got_diff_blob_cb() implementation to compute added/removed line metrics for a given diff. This enables displaying a diffstat with 'got log -d'. As per suggestion from stsp, change tog diff view to display the diffstat by default. ok stsp@

make 'tog log' display the committer handle by default, '@' switches to author People coming from CVS might not expect names of patch contributers to show up in commit history listings, so make things easy for them. discussed with op@

tog: always echo input prompt to bottom left of screen Irrespective of the active view, always echo to the bottom left of the parent view. ok op@

tog: fix typo that breaks log search when in hsplit Ironically, the typo "blocks" log search when in hsplit because we block input on the wrong view! Pass the proper "v" view to nodelay() calls. ok op@

cope with deleted references when reloading the tog log view ok op jamsek

avoid printing harmless errors that can occur when tog exits due to Ctrl-C ok jamsek

fix detection of SIGTERM in tog; this signal was accidentally being ignored ok jamsek
